2. ELIGIBILITY CRITERIA / QUALIFICATION 2.1 Who Can Participate? The EDRP allows wholesale electricity market participants to subscribe retail end users able to provide Load Reduction (Demand Side Resources) by curtailing Load or by shifting Load onto a Local Generator when called upon by the NYISO during emergency conditions. Wholesale market participants are grouped into four broad classes of Curtailment Service Providers (CSPs): Load-Serving Entities (LSEs) as defined in the NYISO Services Tariff that currently serve retail end users capable of Load Reduction or an LSE that subscribes another LSE s Load solely for the purpose of participating in the NYISO EDRP. An individual retail customer taking service as an LSE and enrolled to take service directly from the NYISO to supply its own Load in the NYCA as defined in the NYISO Services Tariff. NYISO-approved Curtailment Customer Aggregators (Aggregators) of retail end users capable of Load Reduction. Aggregators may claim Load Reductions from Demand Side Resources with which they have a contractual arrangement. An Aggregator may join the NYISO as a NYISO Limited Customer. NYISO-approved Curtailment Program End Use Customers (EUC), end-use customers whose Load is normally served by an LSE but who wish to participate directly with the NYISO solely for purposes of the EDRP. Curtailment Program End Use Customers (EUCs) must be capable of reducing at least 100 kw of Load. An EUC is required to join the NYISO as a NYISO Limited Customer. Participation in the EDRP is voluntary. The EDRP program imposes no penalties upon CSPs or Demand Side Resources for not responding to Load Reduction requests; other Load Reduction programs to which the EDRP customer may be simultaneously enrolled, may impose penalties for failure to reduce. Demand Side Resources participating in the NYISO Energy Market or the Ancillary Services Market may also participate in EDRP. 2.2 Minimum Qualifications for CSPs To serve as a CSP, an entity must: 1. Be a NYISO Customer (in the case of LSEs and individual retail customers enrolled as LSEs that take service directly from the NYISO to supply their own Load in the NYCA) or a NYISO Limited Customer (in the case of Aggregators and EUCs) and be able to pledge Load Reduction in the NYCA. 2. Be able to cause a Load Reduction from the NYS Transmission System and/or local distribution system at the direction of the NYISO. Be capable of reducing at least 100 kw of Load per zone. Be capable of responding within two hours of notice from the NYISO. NYISO Demand Response Operations 2-1

Follow the enrollment procedures defined in Section EDRP Enrollment Procedures of this manual. Provide hourly interval metering data to validate performance. Specific metering requirements are given in Section 5 of this manual. 2.3 Restrictions An individual Demand Side Resource can subscribe to either EDRP or the SCR program, but not both. Special Case Resources (SCRs) that have enrolled with the NYISO but have not sold any of their Special Case Resource Capacity will be added to the list of EDRP resources for that period of time when all of their Special Case Resource Capacity is unsold, and will be called with EDRP resources if an EDRP event is deployed. To participate in the Program, an individual Demand Side Resource cannot subscribe the same metered Load with more than one CSP. Information provided by CSPs may be shared with their local Transmission Owner for planning or system operation. Retail end users under a contract that prevents them from curtailing energy are prohibited from participating in the program. Local Generators that are operating to fully serve their Load do not qualify for the EDRP. A Local Generator that is normally operating to partially serve its Load may participate in the program with any additional generation that is available to operate at the direction of the NYISO in order to reduce the remaining Load being supplied from the NYS Transmission System and/or distribution system. Demand Side Resources using a Local Generator to provide load relief through EDRP are subject to all environmental rules and regulations. Demand Side Resources determined not to be complying with environmental requirements will not be permitted to participate in the EDRP. 2.4 Requirements for Curtailment Customers with a Local Generator Owners of Local Generators including, but not limited to, hospitals, data centers, office buildings, warehouses, and industrial locations are eligible to participate in the EDRP. A Local Generator can serve all or part of the facility's Load being supplied from the NYS Transmission System and/or distribution system (i.e., the retail end user s specific Load delivered from their LSE), thereby reducing the total Load being supplied from the NYS Transmission System and/or distribution system during declared emergencies. The requirements for participation are as follow: 1. Be capable of responding within 2 hours of a request to cause a Load Reduction from the NYS Transmission System and/or local distribution system at the direction of the NYISO. 2. Have an integrated hourly or permanent recording meter as described in Section 5.1, Metering Requirements. 3. Be capable of receiving notification from a Curtailment Service Provider (CSP). 2-2 NYISO Demand Response Operations

4. Demand Side Resources that will use Local Generators to reduce Load and that have Load Banks for testing purposes must ensure that the Load Bank is not operating during the hours required by the EDRP. Nothing in the EDRP expands or reduces the rights, obligations, or restrictions a Local Generator may have to buy or sell energy in the NYISO s wholesale market. 2.5 Compatibility with Special Case Resources The EDRP pays for energy during times of emergency, but does not pay for capacity. The NYISO has a separate program called Special Case Resource (SCR) program within the Installed Capacity (ICAP) market that pays for capacity and energy. The SCR program is available to Local Generators and resources that curtail the facility's Load to reduce Load supplied by the NYS Transmission System and/or distribution system during a NYISO initiated performance test or event. SCRs are required to meet testing, metering and other program eligibility requirements. While there are no penalties for non-performance as an EDRP provider, the SCR program will reduce future capacity payments if the NYISO calls for operation and the SCR does not perform. There may also be penalties imposed for nonperformance by other programs in which the SCR resource is simultaneously enrolled. In the event that the NYISO deploys an SCR resource to reduce its consumption of energy in accordance with the criteria set forth in Section 4, the NYISO may deploy the EDRP. SCRs that have enrolled with the NYISO but not sold any of their Special Case Resource Capacity will be added to the list of EDRP resources for the period of time when all of their Special Case Resource Capacity is unsold and will be called with EDRP resources if an EDRP event is deployed. For more details on SCR, see the ICAP Manual, available from http://www.nyiso.com/public/markets_operations/documents/manuals_guides/index.jsp by activating the Operations option in the navigation pane and choosing the Installed Capacity Manual link in the display pane. 2.6 Compatibility with other NYISO Demand Response Programs Demand Side Resources may participate in both the EDRP and the Day-Ahead Demand Response Program (DADRP) offered by the NYISO. If an EDRP event is called and a Demand Side Resource is participating in both programs, payments will be made in accordance with Section 5.4.2 of this EDRP Manual. Demand Side Resources may participate in both the EDRP and the Demand Side Ancillary Services Program (DSASP) offered by the NYISO. If an EDRP event is called and a Demand Side Resource is participating in both programs, the Demand Side Resource's realtime dispatch schedule in the DSASP program will be terminated for the duration of the demand response event to permit the Demand Side Resource to participate as an EDRP resource. If an EDRP event is called and a Demand Side Resource is participating in both programs, payments will be made in accordance with Section 5.4.2 of this Manual. NYISO Demand Response Operations 2-3

2.7 Small Customer Aggregation 1. Aggregations must be at least 0.5 MW for EDRP. The NYISO will establish an up-front means of certifying that the aggregation has an expectation of meeting this requirement. This will be established as part of the approval of the verification methodology; the sampling plan or other measurement methodology will assign an initial (a priori deemed) estimate of the response per site in order to drive the sample size. Resources included in the aggregation may only participate in one NYISO reliability program. The NYISO may request confirmation that all resources are enrolled only for participation in the Emergency Demand Response Program. The aggregation can be comprised of two or more different sampling methods, provided that such a super aggregation was allowed by the NYISO. 2. Aggregators will be held responsible and liable for payments to and penalties levied against the members of the aggregation. 3. Proposals for measuring aggregation performance can involve one of several methods: a. The deployment of approved whole-premise kw metering devices on a sample of resources b. The deployment of approved end-use device or process kw metering devices on a sample of resources that elect to limit EDRP participation to specified end-use devices or processes c. Provision for supplying verifiable behavioral actions, equipment operating logs, or other data that is deemed to be sufficient, indicating the load level the customer otherwise would have consumed, but for the EDRP event participation d. Other measurement systems that indicate the load level the customer otherwise would have consumed, but for the EDRP event participation 4. Small Customer Aggregation: A process and procedures will be drawn to govern how applications are made, processed and ruled upon, and to set limits to aggregation projects by zone, provider, program, or any other category. The number of aggregations allowed needs to accommodate all of the utilities plus a reasonable number of CSPs and LSEs. Each initial proposal (or significant revision thereof) for small customer aggregation will be reviewed by the NYISO staff and the Price Responsive Load Working Group, and must be approved by a majority of the Chairs and Vice-Chairs of the Management Committee and Business Issues Committee and the Chairman of the Price Responsive Load Working Group. 5. The Small Customer Aggregator is responsible for all costs associated with developing and administering the alternative performance methodology. Applications for approval of alternative methodologies must include an explicit description of the methodology and how it would be tracked and administered, accompanied by the specific administration processes required. The NYISO, in approving an application, will specify the costs associated with administration that the applicant must bear. The aggregation applicant must agree to be responsible for all such costs, including costs incurred by the NYISO for developing and administrating the alternative methodology. The NYISO may, at 2-4 NYISO Demand Response Operations

its discretion, require that some or all of such costs be reimbursed by the applicant upon approval of the methodology, or deduct all costs from payments for curtailments by resources, or a combination of the two methods of cost recovery. 6. End-use electricity customers may subscribe Load at a given premise to EDRP only under a single performance methodology, either the standard method or an approved alternative methodology. 7. Failure to comply with aggregation procedures: The NYISO may, at any time, terminate its agreement with an aggregation broker if it determines that the broker is not fulfilling its obligation under the aggregation agreement. Customers belonging to such an aggregation may henceforth participate by signing up under any approved means of participation. 2.8 EDRP Program Evaluation Curtailment Service Providers shall participate in all NYISO-sponsored EDRP program evaluations for which NYISO requires their participation.

3. EDRP ENROLLMENT PROCEDURES 3.1 Requirements for CSP Enrollment To qualify as a Curtailment Service Provider (CSP), an organization must be one of the following: 1. An LSE serving retail Load, 2. An individual customer taking service from an LSE and registered to take service directly from the NYISO to supply its own Load in the NYCA, 3. A Curtailment Customer Aggregator (a NYISO Limited Customer that works with owners of Demand Side Resources to make it easier to participate in the NYISO Emergency Demand Response program), or 4. A Curtailment Program End Use Customer (a NYISO Limited Customer that is a retail end user capable of interrupting Load or using a Local Generator that can reduce at least 100kW in a load zone). For information on becoming a NYISO Customer, see the NYISO web site at http://www.nyiso.com/public/markets_operations/services/nyiso_registration/index.jsp 3.2 Procedures for Enrolling Demand Side Resources in EDRP CSPs are required to obtain authorization from each EDRP resource allowing the CSP to enroll the resource in the EDRP. Upon request, the CSP shall provide such authorization to the NYISO. It is the responsibility of the CSP to ensure compatibility with other curtailment programs before enrolling resources in the EDRP. Demand Side Resources must be enrolled for participation in the EDRP through the NYISO Demand Response Information System (DRIS) according to the DRIS Event Calendar. Information on the type of data that is required in DRIS is provided in the DRIS User s Guide, posted on the NYISO web site at http://www.nyiso.com/public/markets_operations/market_data/demand_response/index.jsp Resources must be reenrolled each Capability Period for participation in the EDRP.

4. OPERATING MECHANISM / IMPLEMENTATION 4.1 When Will the Program be Deployed? The NYISO will deploy the EDRP as one of its emergency procedures in conjunction with the In-day Peak Hour Forecast response to an Operating Reserve Peak Forecast Shortage, as defined in, or in response to, the Major Emergency State as defined in the NYISO Emergency Operations Manual (available from the NYISO Web site at http://www.nyiso.com/public/markets_operations/documents/manuals_guides/index.jsp by activating the Operations option in the navigation pane and choosing the Emergency Operations link in the display pane). Day-ahead notice of a potential operating reserve shortage shall be provided to CSPs when possible. The program is intended to support the New York State power system during emergency periods and the NYISO reserves the right to use its discretion in deploying EDRP resources to relieve system or zonal emergencies. The EDRP may be deployed in conjunction with Special Case Resources. 4.2 NYISO Protocol for Local Generator Participation This section describes the circumstances under which the NYISO and its market participants have agreed that CSPs and RIPs may contract with customers who agree to reduce demand on the electricity grid by offloading all or a portion of their own power needs through the operation of Local Generators to cause a Load Reduction from the NYS Transmission System and/or local distribution system at the direction of the NYISO. 4.2.1 Compliance with Federal, State and Local Laws By enrolling a resource that is a Local Generator, CSPs and RIPs, which may participate in the EDRP program in accordance with Section 2.5 of this manual when capacity associated with its SCRs is unsold, certify that the resource complies with all federal, state, and local laws and regulatory requirements with respect to operation of the Local Generator used to reduce Load on the NYCA system during a demand response event. RIPs that participate in EDRP pursuant to Section 2.5 of this manual and CSPs will provide documentation of compliance with these requirements upon request of the NYISO. 4.3 Notification Procedures When the NYISO deploys the Emergency Demand Response Program (EDRP), a specific set of messages will be sent to Curtailment Service Providers (CSPs). A CSP will be asked to take certain actions in response to the NYISO notification. This section describes the contact procedures and actions that will be requested of CSPs. NYISO Demand Response Operations 4-1

The time frame for advisory and deployment notices will be a function of the degree of warning the NYISO has in identifying and responding to operating reserve shortages / major emergencies. Notification from the NYISO will take place via two communications media: Burst e-mail messages to all CSP Event-Responder e-mail contacts specified in DRIS. Automated phone call to all CSP Event-Responder phone contacts specified in DRIS. After receiving an EDRP notification, the CSP shall take the following steps: 1. Assess whether or not the CSP has resources that can respond, and the kw level of response by zone. 2. Provide the expected kw response by load zone in accordance with the instructions in the notification. 3. If for some reason, the CSP cannot follow the response instructions, the CSP is advised to contact NYISO Stakeholder Services at 518-356-6060. If the NYISO does not receive the automated response in a reasonable amount of time, it may call additional CSP contact numbers in an attempt to make a connection. In this case, NYISO staff will identify themselves by name and indicate that the NYISO has deployed the EDRP program, followed by the specific requests below. Several types of notifications may be distributed. The notification types include, but are not limited to: Day-Ahead Advisory, In-Day Advisory, Activation (2 Hour Notice), Immediate Activation, Extension of an Event, or Early Termination of an Event. The email and phone messages specify the type of notification, hours of event or advisory, and zones called. The exact wording of the notices is subject to change and may include additional information. Listed below are examples of the type of notices that may be received for a Day-Ahead Advisory and Activation (2-Hour Notice). 4.4 Notification Message Examples 4.4.1 EDRP Day-Ahead Advisory This notice applies to Curtailment Services Providers (CSPs) participating in the NYISO Emergency Demand Response Program (EDRP).

5. METERING, VERIFICATION, BILLING, AND SETTLEMENT As provided in ICAP Manual Section 4.12.2, the CSP Metering and Meter Data Requirements provided in Sections 5.1, 5.2 and 5.3 also apply to Responsible Interface Parties (RIPs) with SCR resources in the SCR Program. 5.1 Metering Requirements CSPs must use PSC-certified Meter Service Providers (MSP) or Transmission Owners (TOs) to install, and PSC-certified Meter Data Service Providers (MDSP) to read, revenuegrade interval meters. Installation of any devices directly connected to the revenue meter, such as totalizers, must be performed by PSC-certified MSPs or TOs. Non-revenue-grade meters meeting the 2% accuracy requirement as defined in Section 5.1.1 may be installed by CSPs as long as they are certified by a Professional Engineer as meeting ANSI C12 standards and are periodically tested and calibrated in accordance with the standards applicable to MSPs. Transmission Owner or MDSP certification is required to read the meter. CSPs must use a PSC-certified MDSP to read such meters. Acceptable interval metering for Demand Side Resources participating in the EDRP, whether with Load Reduction, a Local Generator or a combination of both, is described below in Section 5.1.1. 5.1.1 Metering Device Requirements Meters installed under the 2001 EDRP rules prior to March 20, 2002 may be used as the source of EDRP event reporting data. Hourly interval metering data is required to validate performance. Demand Side Resources may use non-revenue interval metering devices with an overall accuracy of ±2% as the source of performance data. For each non-revenue interval meter design used, the CSP will submit certification from the meter manufacturer that the model in use meets the ±2% accuracy threshold, recognizing errors in: Current measurement Voltage measurement A/D conversion Calibration Such meters shall be periodically tested and calibrated in accordance with the standards applicable to MSPs and MDSPs. Where a revenue meter exists, losses in secondary/service circuits between the revenue meter and the non-revenue interval meter may be compensated for to bring the reading within ±2% of the revenue meter. The CSP must demonstrate compliance through comparison of the revenue and non-revenue meters, or show calculation of losses between the revenue and non-revenue meters. NYISO Demand Response Operations 5-1

5.1.2 Metering Configuration Requirements A CSP must identify a "Response Type" for each EDRP resource it enrolls in DRIS based upon: (i) how the EDRP resource will reduce its Load during a NYISO initiated event; and (ii) the meter configuration of the EDRP resource's facility. Each EDRP resource must be enrolled as one of the following: Response Type C (Curtailment), Response Type G (Generation), or Response Type B (Both). An EDRP resource must enroll as Response Type C when it reduces the Load supplied by the NYS Transmission System and/or distribution system during a NYISO initiated event only by curtailing the facility's Load, and that submit the entire facility's net meter data as evidence of Load reduction. An EDRP resource must enroll as Response Type G when it reduces the Load supplied by the NYS Transmission System and/or distribution system during a NYISO initiated event only by using a Local Generator, and submits the Local Generator's meter data (not entire facility's net meter data) as evidence of Load reduction An EDRP resource must enroll as Response Type B when: (i) it uses both a Local Generator and curtailment of the facility's Load to reduce Load supplied by the NYS Transmission System and/or distribution system during a NYISO initiated event, and submits (a) the entire facility's net meter data, or (b) the net of entire facility's Load meter data and Local Generator's meter data as evidence of Load reduction; or (ii) it uses only a Local Generator to reduce the Load supplied by the NYS Transmission System and/or distribution system during a NYISO initiated event, and submits (a) the entire facility's net meter data, or (b) the net of entire facility's Load meter data and Local Generator's meter data as evidence of Load reduction. Figure 5-1 illustrates examples of acceptable EDRP resource meter configurations. The Local Generator represented in the illustrations is used to facilitate Load reduction. For use of any meter configuration not represented by one of these diagrams, please contact NYISO Stakeholder Services at 518-356-6060. 5-2 NYISO Demand Response Operations

Figure 5-1 Examples of acceptable Meter Configurations 5.1.3 Historical Operating Data Upon request of the NYISO, CSPs and RIPs shall provide historical metering and operating data for each resource enrolled that is consistent with the enrolled meter configuration. These requirements may be met by, but not limited to, the following types of data requests: 1. For a resource that is participating in the EDRP, the meter ID and MSP ID certifying meter installation; 2. For resources with existing interval meters, a minimum of 30 days of hourly interval data immediately preceding the first month of the Capability Period the resource will participate in; 3. For resources that are eligible to report totalized Loads with existing interval meters, hourly interval data for a minimum of 30 days of hourly interval data for all participating Loads at the premise. Consistent with Section 4.12.7 of the ICAP Manual, RIPs and CSPs shall retain all interval meter readings upon which it bases its certification of compliance for a period of three (3) years. 5.2 Calculation of CBL 5.2.1 Select a CBL method 1. The CSP selects the CBL formula when it enrolls a resource with the NYISO in the EDRP. The choice of CBL becomes effective when the NYISO accepts the enrollment. 2. At the initial enrollment in the EDRP, the CSP may elect either the Average Day CBL or the Adjusted CBL formula. NYISO Demand Response Operations 5-3

3. A change in the CBL formula can be made when the CSP reenrolls the resource in the EDRP in the next Capability Period. 5.2.2 CBL Calculation Method (Load Reduction or Both Local Generator and Load Reduction) Based on DRIS Metering Configuration It is the responsibility of the CSP to provide the CBL calculation to the NYISO and ensure that calculations are complete and accurate. Section 5.2.3 provides a complete example of the CBL calculation process including the weather adjustment. Any Load supported by generation produced from a Local Generator, other behind-themeter generator, or other supply source located behind the resource's meter may not be included in the metered Load used to calculate the resource's CBL when the resource is enrolled in DRIS with a Response Type B or C. Resources enrolled in DRIS with a Response Type G are required to use the CBL Calculation Method in Section 5.2.4 for calculation of the CBL of the Local Generator to calculate energy response during a demand response event. I. The Average Day CBL for Weekdays I.A. Establish the CBL Window for Weekdays. I.A.1. Determine the resource's peak load hour within, but not to exceed, the last 30 days that corresponds to the hours that cover the event for which the CBL is being developed. Multiply the peak load hour value by 25% to calculate the initial seed value. (Figure 5-2) I.A.2. Beginning with the day prior to the event for which the CBL is being calculated, exclude the following: I.A.2.a Any holidays within the last 30 days, as specified by the NYISO. I.A.2.b Any days within the last 30 days when the NYISO declared an SCR, EDRP or TDRP event for which the resource was eligible for payment for a curtailment. The day prior to any other weekday when the NYISO declared an SCR, EDRP or TDRP event within the last 30 days for which the resource was eligible for payment for a curtailment. I.A.2.c Any days within the last 30 days in which the resource s DADRP curtailment bid was accepted in the DAM, whether or not the resource actually curtailed. Any day prior to the day in which the resource's DADRP curtailment bid was accepted in the DAM, whether or not the resource actually curtailed. I.A.3. For each remaining weekday within the last 30 days, create the Average Daily Event Period Usage for that day, defined as the simple average of the resource s actual usage over the hours that define the event for which the CBL is being developed. Eliminate low usage days. For each day that has not been excluded within the last 30 days, compare the resulting Average Daily Event Period Usage to the initial seed value. If the Average Daily Event Period Usage is less than the initial seed value, exclude that day. If, after all 5-4 NYISO Demand Response Operations
